I've been playing a lot of Dragon Age Inquisition lately. The costume and armor designs from that game were big influences on these two Toa.

The only problem is that I can't decide what they are Toas of. Anybody have any suggestions? On IG the best ones so far are 'thunder and lightning' and 'ice and acid'.

The chest, hands, and feet on Vhisim are painted. I tried to match Lego's original green, but I missed the mark by several shades. So instead he's sort of a military green. It could have been worse I suppose.

If you want to remain strictly canonical, I'd go with Lightning and Plant Life/Jungle/The Green. Eltarin's color-scheme, especially with the yellow cape, screams Lightning to me, while Vhisim's white, being the unique whitish-blue color from Thok, can reasonably pass as a variation on Plant Life's standard blue-green color-scheme. If you want to go with non-canonical Elements, I think almost anything could work. It'd be interesting, perhaps, to assign Vhisim an Element based upon one of his colors, and then explain the others as armor upgrades or patches, since he's got a lot going on.

As for the MOCs themselves, they are very nice, as always. The arm construction is quite ingenious, especially given its simplicity, and it makes these two very well-proportioned. I like the way the swords on their torsos function, but it does strike me as slightly odd-looking. They seem to be necessary for the head attachment, however, so I don't think removing them is necessary, especially since they do look quite a bit better in more the dynamic poses.

@Toa_Heatwave This is a great response. Much more detailed than the others I've received. I like the idea of yellow representing lightning. I should modify his weapon a little bit to reflect that power.

I don't know about Vhisim being plantlife though. All of the colors would fit that, except the copper. But you're not the only one who suggested it. On IG others have as well.
